Abstract: A fluid monitoring apparatus includes a housing and a tracer sensor attached to an exterior of the housing. The housing has at least one flow passage for a fluid sample and a port for the tracer sensor to monitor the fluid sample in the housing. In one example, the monitoring apparatus may include a plurality of tracer sensors attached to the housing, wherein the tracer sensors are interchangeably attached to the housing. In one embodiment, the monitoring apparatus may be attached to a first well for detecting the presence of a tracer in the first well, wherein the tracer is supplied from a second well.

Abstract: A centrifuge (1) includes: a motor (4) having a rotor (3); an imaging system (2) torsionally connected to the rotor; a sample holder torsionally connected to the imaging system; and a light source (7) for illuminating the sample holder. The imaging system includes: a image sensor in optical communication with the sample holder; and a data link for transmitting image data. A centrifuge test includes: spinning a reservoir core sample in a sample holder of a rotor, wherein an imaging system is torsionally connected to the rotor; and collecting image data of the sample holder with the imaging system while spinning.
